How long does it take your battery to charge?

One frustration I'm having currently is that my battery on the Ally take forever to charge. I am using the included charger cable and adapter - and pluggin straight into the wall - so its not an issue of charging from a laptop - or usb port or something. This is straight from a power outlet.

It seems to take several hours to charge the phone from ~30% to 100%. For example, I was at 38% and plugged in my phone - went to lunch. An hour later I checked and my phone was at 46%. That's SLOOOW.

Be VERY careful with anything that claims to charge a LiPo battery in under an hour, charging a LiPo battery at over 1c can be a VERY bad idea. That being said, the battery in our phones SHOULD be able to take 1.5a input for charging, BUT heat may be an issue, and I'm not sure if the phone will handle current that high (an external battery charger should be able to, but be sure to keep it cool during the charge.

I just got my phone and was doing my first charge and like you, it took about an hour just to get through the first 15%. I then decided to take a walk so I put my phone on silent mode and airplane mode and also turned the screen off. When I got back from my walk about an hour later, it had charged all the way up to 45%. That's twice as much charge as the first hour. Don't know which one had more of an impact, but obviously by switching to airplane mode and turning the screen off, the phone wasn't using battery power while it was trying to charge so it was able to charge quicker. Try those two things and see if you have any better luck.

I have a universal external battery charger, that I would have to double check the specs on, since I don't have it in front of me. It has two contacts on it that you move around to get the right distance from one spot to another on the battery and I've been using that for my 2 regular Ally batteries and my primary extended one. I typically run the batteries to down near 15 % according to the Ally's stats and charge them from there. I know it takes a while to charge (usually at least 3-4 hrs) but thankfully, I usually manage to have at least one of the others charged, if not two. I would LOVE to get a legit LG standalone battery charger, but since I'm not always anywhere near an outlet, I carry spare batteries instead.

When I plug my phone in, it automatically turns on the screen. I always then turn it off

(but I did set somewhere in the main settings that it should stay on while plugged in).

Also, do you have your GPS radio turned on?

And/or possibly WiFi is on?

Next to look for things that are running unnecessarily :

Main-screen -> settings -> About Phone -> Battery use ... this will show you a sorted bar-graph of what has used most of your battery power

Main-screen -> settings -> applications -> Running Services

Also you can use any of the available (generally free) "App-Killer" programs that will show you (possibly via optional-settings) what the CPU utilization of your currently running programs is (although none that I have tried so far show graphs or accumulations of CPU total use the way the Battery-use graph does).

Next alternative possibility is if nothing looks like it has excessive battery use above is to see if either your Ally or the charger pod seems warm ... bad charger pods get hot due to internal electrical resistance. Alternatively, an Ally that claims no unusual heave use on the Battery-use page but is itself hot could be an internal bad circuit or improper wiring in the charger pod delivering voltage across USB badly.

One possible test would be to try another_high_quality_ 0.85A or 1.0A USB charger pod from an ipod-touch or another Android device (not cheap-from-ebay-from-China, which generally perform poorly as I was posting about above). Note that many computers output only 0.5A, which is enough only to keep an Ally level, not to give any worthwhile % per hour increase.
